JP7240636B2 - Rectangular pipes for piping inside and outside buildings and parts for their joints - Google Patents

Description

The present invention provides a substantially rectangular pipe for indoor/outdoor piping, which can be easily installed on the wall surfaces of the interior and exterior of a building, and which can be decoratively attached to the wall surface. It relates to joint parts.

In general, pipe materials used in various facilities such as water supply and drainage, sewage, rainwater equipment, fire extinguishing equipment, air piping, etc. in stores and factories, etc., and connecting devices for various pipe materials are circular steel pipes and resin pipes. In many cases, it is buried in the wall or in the soil because of the unattractive appearance. Therefore, installation is difficult.
In addition, many circular pipes are laid in parallel in factories, etc., but rectangular pipes require less space and are more economical due to lower packaging, transportation, and storage costs.

Circular steel pipes and vinyl pipes are common for building pipes, and pipes with shapes other than circular are rare. ing. An ovoid tube having an oval cross section in which a large-diameter arc portion and a small-diameter arc portion are connected by a curved line has been proposed (see Patent Document 1).
2. Description of the Related Art Steel pipes used as water pipes such as water supply and drainage pipes are coated with a resin on the inner surface thereof in order to impart corrosion resistance to the inner surface thereof. For example, steel pipes with vinyl chloride resin affixed to the inner surface are widely used in general. Due to the low impact resistance of vinyl chloride resin, vinyl chloride resin may be damaged, making it difficult to maintain corrosion resistance. Furthermore, a method has been proposed in which the steel pipe and the vinyl chloride resin are separated from each other and disposed of separately so that harmful substances are not generated from the vinyl chloride resin after the steel pipe coated with hard PVC on the inside surface is used.

Therefore, techniques for coating the inner surface of steel pipes without using vinyl chloride resin are being studied. A technique is disclosed in which a crosslinked polyethylene pipe is imparted with shape-restoring properties, expanded in diameter by heat restoration in the steel pipe, and coated on the inner surface of the steel pipe. Further, a technique has been disclosed in which the inner surface of a steel pipe is coated by imparting shape-restoring properties to a polyethylene pipe (see Patent Literatures 1 and 2).

In addition, assuming that there is no above-mentioned problem, most of the piping technology is a countermeasure against the accumulation of solids inside the pipe or corrosion, and proposals for pipe shapes are made for decoration or simplification in piping work. very few.

In shops, factories, etc., when underground piping under the floor leaks due to aging or earthquakes, it is difficult to determine the leaking point, and the construction is forced to peel off the floor surface concrete and large-scale construction. Furthermore, in factories, machinery is relocated or operations are temporarily suspended, and in stores, large damage such as the movement of display items cannot be avoided.
For this reason, the existing underground piping will be abolished, and exposed piping will be branched from near the meter for tap water, near the pump for well water, or near the building where there is no obstruction, and will be exposed along the outdoor wall. From there, there is no choice but to branch further indoors and use it. However, if it is outdoors, there is a risk of water leakage due to pipe bursting due to freezing in winter, so insulation is required. In addition, exposed indoor piping is unattractive and gives a sense of discomfort.
Also, when a large number of pipes need to be laid in parallel in a factory or the like, a wide piping space is required, and a pipe with a shape that allows piping even in a narrow space is desired.

Specially designed for pipe materials used in various facility equipment such as water supply and well water supply and drainage, sewage, rainwater, fire extinguishing, etc., such as houses, stores, offices, factories, warehouses, etc. Shaped tubing is expected. In particular, when pipes buried in factories, stores, offices, and houses leak water, the construction can be done easily without the need for large-scale construction work such as stripping the floor concrete, and it will not be in a state like the remains of waterworks. For tap water, rectangular pipes are used so that there is no damage to the decoration inside and outside the building, and it can be easily installed indoors. Therefore, there is a demand for construction that does not look good and does not give a sense of incongruity to exposed indoor piping. The purpose is to solve the problems of conventional water and gas piping, such as simplification and decorativeness.

In addition to water supply pipes, drainage pipes, sewage pipes, rainwater pipes used inside and outside buildings such as houses, factories, restaurants, offices, public facilities, etc.・We devised a rectangular pipe for circular pipes of various diameters.
A steel pipe or a resin pipe that can be piped on the walls inside and outside the building and can be attached to the walls, and has a rectangular cross section with rounded corners in an R-curved surface, and a double-ended rectangular shape with a vertical width of 10. The ratio of length to width is 1:2 to 1:4 for ~20 m, the thickness of the tube is 2 to 5 mm, the appearance of the rectangular tube is thick plate-like, and the outer surface is various single colors and It has a decorative pattern.

The outer surface of the rectangular tube, which has a thick plate-like shape, is colored, and various patterns, pictures, or photographs are printed directly, or printed on paper or resin and pasted with an adhesive. 2. Rectangular pipes for piping inside and outside a building and their joint parts, which are decorated so as not to make the surroundings of the building look strange .

The rectangular pipe has a width of 2 to 4 mm at the rounded corners and a length of 2 to 4 m. I have a

The inner diameters of the connector , which is an accessory part for adding, bending, and branching a thick plate-shaped rectangular pipe, and the elbow, tee, and socket of the same pipe shape as a sealing device, are rectangles with a thick plate shape at the fitting type joint. It has the same shape and size as the outer shape of the tube with a difference of ±0.2 mm, and the outer surface of the accessory part also has a decorative pattern.

According to the present invention, appearance is an important factor in the case of piping in a building, and a design that does not create a sense of incongruity is required, especially in shops, restaurants, and the like visited by customers. In addition, in the case of a factory that requires a large number of pipes, in order to allow many pipes to be installed in a small space, the cross section of the pipe is rectangular, and the four corners are rounded to create a plate-like appearance to solve the problem. By choosing colors and pictograms that match indoor and outdoor wall colors, you can expand the range of uses. Space can be created.

In addition, it is generally used for pipe materials used in various facility equipment such as water supply and well water supply and drainage, sewage, rainwater, fire extinguishing, etc. in houses, stores, offices, factories, warehouses, etc. In particular, the pipe can be installed directly on the wall of the building without being buried inside the wall or in the ground, so the construction is easy and the construction period is short. Costs are reduced in packaging, transportation and storage. In addition, since it is not possible to excavate the underground pipes in a narrow site by hand, the excavation width is narrow and the excavation labor is greatly reduced, which is expected to shorten the time.
